I wonder why that is. Is this the file where function "main" is
reported to be?

In terms of the GDB implementation, you can start by looking at what
we do in symtab.c:find_main_name(). What you need to do is find a way
for GDB to determine what the name of the main routine is. See the
comment I inserted that explains also that we should not have any
false positive.

In terms of the Fortran compiler, I don't know how things are setup,
so I don't know how it actually needs to be done, or if it's doable
at all, actually.  It looks like, from the patch that Daniel posted,
that this routine is always called "MAIN__". Is that the case?
